What channels are involved in the repolarization of a cardiomyocyte?
What is the name of a channelopathy that causes syncopal episodes, lethal tachyarrthmias, and ventricular tachyarrthmias that is autosomal dominant or recessive?
Long-QT syndrome (LQTS)
Long-QT syndrome (LQTS) does what to the QT segment?
QT indicates the ventricular repolarization or recovery, therfore the QT interval is significantly prolonged, ventricular repolarization is delayed, leading to increased risk of ventricular tachyarrhythmias.
The majority of the genes involved with LQTS (long QT-syndrome) involve what ion channel??
Because K+ channels are a huge part of ventricular repolarization, if you have problems with K+ channels, you have prolonged ventricular repolarization, and a longer QT interval.
LQT Syndrome involves mutations to what ion channels?
